Free Encrypted Accounting Software
Every mainstream accounting app — QuickBooks, Xero, Wave, Zoho Books, FreshBooks — stores your business data on their servers in a format they can read. One breach, one malicious insider, one government subpoena, and your entire financial history is exposed. BusinessOS was built the opposite way.
Try it now →What zero-knowledge means
- Your password is the only key that decrypts your data
- The key is derived on your device — we never see it
- All server-stored data is encrypted before it uploads
- If we get breached, hacked, or subpoenaed, the attacker gets encrypted bytes
- If you forget your password, even we cannot recover your data (use a password manager)
Who needs encrypted accounting
- Lawyers handling client billing
- Doctors and therapists tracking patient invoices
- Consultants with sensitive client contracts
- Real estate agents with buyer/seller commissions
- Any business owner who values confidentiality
How this compares
QuickBooks, Xero, Wave, Zoho, and FreshBooks all store your data unencrypted on their servers. Their terms of service allow them to use your data for advertising, product improvement, and — increasingly — AI training. BusinessOS cannot do any of that, because we cannot read your data.
